Chinese people
–
The Han Chinese, Han people or simply Han are an ethnic group native to East Asia. They constitute approximately 92% of the population of China, 95% of Taiwan, 76% of Singapore, 23% of Malaysia, Han Chinese are the worlds largest ethnic group with over 1.3 billion people. Similarly, the Chinese language also came to be named the Han language ever since, in the Oxford Dictionary, the Han are defined as The dominant ethnic group in China. In the Encyclopedia of the Peoples of Asia and Oceania, the Han are called the dominant population in China, as well as in Taiwan, according to the Merriam-Webster Dictionary, the Han are the Chinese peoples especially as distinguished from non-Chinese elements in the population. The name Hanzhong, in turn, was derived from the Han River, which flows through the regions plains. The river, in turn, derives its name from such as Tianhan, Yinhan, Xinghan or Yunhan, all ancient Chinese poetic nicknames for the Milky Way. This gave rise to a commonly used nowadays by overseas Chinese for ethnic identity – Huaren. The term is used in conversation and is also an element in the Cantonese word for Chinatown. The vast majority of Han Chinese – over 1.2 billion of them – live in areas under the jurisdiction of the Peoples Republic of China, where they constitute about 92% of its population. Han Chinese also constitute the majority in both of the administrative regions of the PRC—about 95% and 96% of the population of Hong Kong and Macau. There are over 22 million Han Chinese in Taiwan, they began migrating from the coastal provinces of mainland China to Taiwan during the 13th to 17th century. At first, these migrants chose to settle in locations that bore a resemblance to the areas they had left behind in mainland China, hoklo immigrants from Quanzhou settled in coastal regions, and those from Zhangzhou tended to gather on inland plains, while the Hakka inhabited hilly areas. Clashes between these groups over land, water, and cultural differences led to the relocation of some communities, of about 40 million overseas Chinese worldwide, nearly 30 million live in Southeast Asia. They are collectively called Nanyang Chinese, according to a population genetic study, Singapore is the country with the biggest proportion of Hans in Southeast Asia. Up until the past few decades, overseas Han communities originated predominantly from areas in southern China, christmas Island has a Chinese majority at 70%, large Chinese populations also live in Malaysia and Thailand. Prior to the 1965 split, Malaysia and Singapore used to have the largest overseas Chinese population in the world and this position has since been taken by Thailand. The prehistory of the Han ethnic group is closely intertwined with both records and mythology. Han Chinese trace their ancestry from a confederation of late neolithic/early bronze-age agricultural tribes that lived along the Guanzhong, the Yellow Emperor is traditionally credited to have united with the neighbouring Shennong tribes after defeating their leader, Flame Emperor, at the Battle of Banquan

Xinjiang
–
Xinjiang, officially the Xinjiang Uyghur Autonomous Region, is a provincial-level autonomous region of China in the northwest of the country. It is the largest Chinese administrative division and the 8th largest country subdivision in the world and it contains the disputed territory of Aksai Chin, which is administered by China. Xinjiang borders the countries of Mongolia, Russia, Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan, the rugged Karakoram, Kunlun, and Tian Shan mountain ranges occupy much of Xinjiangs borders, as well as its western and southern regions. Xinjiang also borders Tibet Autonomous Region and the provinces of Gansu, the most well-known route of the historical Silk Road ran through the territory from the east to its northwestern border. In recent decades, abundant oil and mineral reserves have been found in Xinjiang and it is home to a number of ethnic groups, including the Han, Kazakhs, Tajiks, Hui, Uyghur, Kyrgyz, Mongols, and Russians. More than a dozen autonomous prefectures and counties for minorities are in Xinjiang, older English-language reference works often refer to the area as Chinese Turkestan. Xinjiang is divided into the Dzungarian Basin in the north and the Tarim Basin in the south by a mountain range, only about 4. 3% of Xinjiangs land area is fit for human habitation. With a documented history of at least 2,500 years, the territory came under the rule of the Qing dynasty in the 18th century, which was later replaced by the Republic of China government. Since 1949, it has been part of the Peoples Republic of China following the Chinese Civil War, in 1954, Xinjiang Bingtuan was set up to strengthen the border defense against the Soviet Union, and also promote the local economy. In 1955, Xinjiang was turned into a region from a province. In the last decades, there have been tensions regarding Xinjiangs political status, amnesty International said that activists in Xinjiang have been arrested and tortured. Under the Han dynasty, which drove the Xiongnu empire out of the region in 60 BC, Xinjiang was previously known as Xiyu or Qurighar and this was in an effort to secure the profitable routes of the Silk Road. Dzungaria was known as Zhunbu and the Tarim Basin was known as Huijiang during the Qing dynasty before both regions were merged and became the region of Gansu Xinjiang, later simplified as Xinjiang. The name Xinjiang, which literally means New Frontier or New Borderland, was given during the Qing dynasty, according to the Chinese statesman Zuo Zongtangs report to the Emperor of Qing, Xinjiang means an old land newly returned. For instance, present-day Jinchuan County was known as Jinchuan Xinjiang, in the same manner, present-day Xinjiang was known as Xiyu Xinjiang and Gansu Xinjiang. After 1821, the Qing changed the names of the other regained regions, the name East Turkestan was created by Russian sinologist Hyacinth to replace the term Chinese Turkestan in 1829. East Turkestan was used traditionally to only refer to the Tarim Basin, in 1955, Xinjiang province was renamed Xinjiang Uyghur Autonomous Region. The name that was proposed was simply Xinjiang Autonomous Region

China
–
China, officially the Peoples Republic of China, is a unitary sovereign state in East Asia and the worlds most populous country, with a population of over 1.381 billion. The state is governed by the Communist Party of China and its capital is Beijing, the countrys major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a power and a major regional power within Asia. Chinas landscape is vast and diverse, ranging from forest steppes, the Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from much of South and Central Asia. The Yangtze and Yellow Rivers, the third and sixth longest in the world, respectively, Chinas coastline along the Pacific Ocean is 14,500 kilometers long and is bounded by the Bohai, Yellow, East China and South China seas. China emerged as one of the worlds earliest civilizations in the basin of the Yellow River in the North China Plain. For millennia, Chinas political system was based on hereditary monarchies known as dynasties, in 1912, the Republic of China replaced the last dynasty and ruled the Chinese mainland until 1949, when it was defeated by the communist Peoples Liberation Army in the Chinese Civil War. The Communist Party established the Peoples Republic of China in Beijing on 1 October 1949, both the ROC and PRC continue to claim to be the legitimate government of all China, though the latter has more recognition in the world and controls more territory. China had the largest economy in the world for much of the last two years, during which it has seen cycles of prosperity and decline. Since the introduction of reforms in 1978, China has become one of the worlds fastest-growing major economies. As of 2016, it is the worlds second-largest economy by nominal GDP, China is also the worlds largest exporter and second-largest importer of goods. China is a nuclear weapons state and has the worlds largest standing army. The PRC is a member of the United Nations, as it replaced the ROC as a permanent member of the U. N. Security Council in 1971. China is also a member of numerous formal and informal multilateral organizations, including the WTO, APEC, BRICS, the Shanghai Cooperation Organization, the BCIM, the English name China is first attested in Richard Edens 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. The demonym, that is, the name for the people, Portuguese China is thought to derive from Persian Chīn, and perhaps ultimately from Sanskrit Cīna. Cīna was first used in early Hindu scripture, including the Mahābhārata, there are, however, other suggestions for the derivation of China. The official name of the state is the Peoples Republic of China. The shorter form is China Zhōngguó, from zhōng and guó and it was then applied to the area around Luoyi during the Eastern Zhou and then to Chinas Central Plain before being used as an occasional synonym for the state under the Qing

Jiangsu
–
Jiangsu, formerly romanized as Kiangsu, is an eastern-central coastal province of the Peoples Republic of China. It is one of the provinces in manufacturing electronics and apparel items. Jiangsu is the third smallest, but the fifth most populous, Jiangsu has the second-highest GDP of Chinese provinces, after Guangdong. Jiangsu borders Shandong in the north, Anhui to the west, Jiangsu has a coastline of over 1,000 kilometres along the Yellow Sea, and the Yangtze River passes through the southern part of the province. Since the Sui and Tang dynasties, Jiangsu has been an economic and commercial center. Cities such as Yangzhou, Nanjing, Wuxi, Suzhou and Shanghai are all major Chinese economic hubs, since the initiation of economic reforms in 1990, Jiangsu has become a focal point for economic development. It is widely regarded as Chinas most developed province measured by its Human Development Index, Jiangsu is home to many of the worlds leading exporters of electronic equipment, chemicals and textiles. It has also been Chinas largest recipient of foreign investment since 2006. Its 2014 nominal GDP was more than 1 trillion US dollars and its name is a compound of the first elements of the names of the two cities of Jiangning and Suzhou. The abbreviation for this province is 苏, the character of its name. The state of Wu was subjugated in 473 BC by the state of Yue, Yue was in turn subjugated by the powerful state of Chu from the west in 333 BC. Eventually the state of Qin swept away all the other states, during the Three Kingdoms period, southern Jiangsu became the base of the Eastern Wu whose capital, Jiankang, is modern Nanjing. When nomadic invasions overran northern China in the 4th century, the court of the Jin Dynasty moved to Jiankang. Cities in southern and central Jiangsu swelled with the influx of migrants from the north, Jiankang remained as the capital for four successive Southern Dynasties and became the largest commercial and cultural center in China. The Tang Dynasty relied on southern Jiangsu for annual deliveries of grain and it was during the Song Dynasty, which saw the development of a wealthy mercantile class and emergent market economy in China, that south Jiangsu emerged as a center of trade. From then onwards, south Jiangsu, especially cities like Suzhou or Yangzhou, would be synonymous with opulence. Today south Jiangsu remains one of the richest parts of China, the Mongols took control of China in the thirteenth century. The Ming Dynasty, which was established in 1368 after driving out the Mongols who had occupied China, following a coup by Zhu Di, however, the capital was moved to Beijing, far to the north

Zhejiang
–
Zhejiang, formerly romanized as Chekiang, is an eastern coastal province of China. The provinces name derives from the Zhe River, the name of the Qiantang River which flows past Hangzhou. Kuahuqiao culture was a neolithic culture that flourished in Hangzhou area in 6. Zhejiang was the site of the Neolithic cultures of the Hemudu, the area of modern Zhejiang was outside the major sphere of influence of the Shang civilization during the second millennium BC. Instead, this area was populated by peoples known as Dongyue. The kingdom of Yue began to appear in the chronicles and records written during the Spring, according to the chronicles, the kingdom of Yue was in northern Zhejiang. Shiji claims that its leaders were descended from the Shang founder Yu the Great, the Song of the Yue Boatman was transliterated into Chinese and recorded by authors in north China or inland China of Hebei and Henan around 528 BC. The song shows that the Yue people spoke a language that was mutually unintelligible with the dialects spoken in north, the Sword of Goujian bears bird-worm seal script. Yuenü was a swordswoman from the state of Yue, to check the growth of the kingdom of Wu, Chu pursued a policy of strengthening Yue. Under King Goujian, Yue recovered from its early reverses and fully annexed the lands of its rival in 473 BC, the Yue kings then moved their capital center from their original home around Mount Kuaiji in present-day Shaoxing to the former Wu capital at present-day Suzhou. With no southern power to turn against Yue, Chu opposed it directly and, in 333 BC, yues former lands were annexed by the Qin Empire in 222 BC and organized into a commandery named for Kuaiji in Zhejiang but initially headquartered in Wu in Jiangsu. Kuaiji Commandery was the power base for Xiang Liang and Xiang Yus rebellion against the Qin Empire which initially succeeded in restoring the kingdom of Chu. At the beginning of the Three Kingdoms era, Zhejiang was home to the warlords Yan Baihu and Wang Lang prior to their defeat by Sun Ce and Sun Quan, who eventually established the Kingdom of Wu. Despite the removal of their court from Kuaiji to Jianye, they continued development of the region, industrial kilns were established and trade reached as far as Manchuria and Funan. Zhejiang was part of the Wu during the Three Kingdoms, Wu, commonly known as Eastern Wu or Sun Wu, had been the economically most developed state among the Three Kingdoms. The historical novel Romance of the Three Kingdoms records that Zhejiang had the best-equipped, the story depicts how the states of Wei and Shu, lack of material resources, avoided direct confrontation with the Wu. In armed military conflicts with Wu, the two states relied intensively on tactics of camouflage and deception to steal Wus military resources including arrows and bows, the other two centers in the south were Jiankang and Chengdu. In 589, Qiantang was raised in status and renamed Hangzhou, some may have lost social privilege, and took refugee in areas south to Yangtze River

Wenzhou
–
Wenzhou is a prefecture-level city in southeastern Zhejiang province in the Peoples Republic of China. Wenzhou is located at the south east of Zhejiang Province with its borders connecting to Lishui on the west, Taizhou on the north. It is surrounded by mountains, the East China Sea, and 436 islands, while its lowlands are almost entirely along its East China Sea coast, most of Wenzhous area is mountainous as almost 76 percent of its 11, 784-square-kilometre surface area is classified as mountains and hills. It is said that Wenzhou has 7/10 mountains, 1/10 water, Wenzhou, which translates to a mild and pleasant land, derives its name from its climate, as it is neither extremely hot in summer nor extremely cold in the winter. Originally known as Yongjia, Yung-chia or Yungkia, Wenzhou was a prosperous treaty port. Wenzhou people make up a number of ethnic Chinese residents of Italy, France. Wenzhou has a history which goes back to about 2500 BC, when it became known for its production as one of the cities of origin of celadon in ancient China. Around 760AD in Tang Dynasty, the founding emperor Emperor Gaozu of Tang named Yongkia by its current name Wenzhou because of its mild weather, throughout its history, Wenzhous traditional economic role has been as a port giving access to the mountainous interior of southern Zhejiang Province. In early European sources, the name Wenzhou-Fu or -Foo was often transcribed Ouen-tcheou-fou after the accounts of French-speaking missionaries, in 1876, Wenzhou was opened for tea exports, but no foreign settlement was ever established there. Between 1937 and 1942, during the Second Sino-Japanese War, Wenzhou achieved importance as one of the few ports still under Chinese control and it declined in the later years of the war, but began to recover after coastal trade along the Zhejiang coast was re-established in 1955. When Guo Pu climbed to the top of West Guo Mountain in Wenzhou, he saw the range of mountains of Wenzhou together shaped as dipper and the city itself aside from mountains shaped as key. Therefore, Wenzhou is now nicknamed as the dipper city based on the popular geographical saying of the city mountains as dipper. Legends have it that during the time when Wenzhou was being established and developed, today, the Deer City District is the name of downtown Wenzhou and White Deer theater located at downtown is the most popular theater among the locals. Wenzhou is the city in China designed by the founder of Fengshui philosophical system Guo Pu. Nowadays, the local Wenzhounese people usually see Guo Pu as the architect, in 2003, the local Wenzhou government built and put up a statue of Guo Pu in downtown Wenzhou. Being the only city in China and the world designed by the pioneer of Fengshui, Wenzhou is usually considered as the city in China with the best Feng Shui condition. Other cities in China that are considered to possess excellent Fengshui nature are Beijing, Ili Kazakh Autonomous Prefecture, Kunming, Hengyang. However, none of these cities is designed entirely on the basis of philosophy of Fengshui or designed by the father of Fengshui Guo Pu, moreover, Wenzhou has an enormous cultural impact and influence on the history of China

Sagittarius (constellation)
–
Sagittarius is one of the constellations of the zodiac. It is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy and its name is Latin for the archer, and its symbol is, a stylized arrow. Sagittarius is commonly represented as a centaur pulling-back a bow and it lies between Scorpius and Ophiuchus to the west and Capricornus to the east. The center of the Milky Way lies in the westernmost part of Sagittarius, as seen from the northern hemisphere, the constellations brighter stars form an easily recognizable asterism known as the Teapot. The stars δ Sgr, ε Sgr, ζ Sgr, and φ Sgr form the body of the pot, λ Sgr is the point of the lid, γ2 Sgr is the tip of the spout and these same stars originally formed the bow and arrow of Sagittarius. Marking the bottom of the teapots handle (or the shoulder area of the archer, are the bright star Zeta Sagittarii, named Ascella, and the fainter Tau Sagittarii. The constellation as a whole is often depicted as having the appearance of a stick-figure archer drawing its bow. Sagittarius famously points its arrow at the heart of Scorpius, represented by the reddish star Antares, following the direct line formed by Delta Sagittarii and Gamma2 Sagittarii leads nearly directly to Antares. Fittingly, Sagittarii is Alnasl, the Arabic word for arrowhead, and Delta Sagittarii is called Kaus Media, Kaus Media bisects Lambda Sagittarii and Epsilon Sagittarii, whose names Kaus Borealis and Kaus Australis refer to the northern and southern portions of the bow, respectively. α Sgr despite having the alpha appellation, is not the brightest star of the constellation, instead, the brightest star is Epsilon Sagittarii, at magnitude 1.85. Sigma Sagittarii is the constellations second-brightest star at magnitude 2.08, Nunki is a B2V star approximately 260 light years away. Nunki is a Babylonian name of origin, but thought to represent the sacred Babylonian city of Eridu on the Euphrates. Zeta Sagittarii, with apparent magnitude 2.61 of A2 spectra, is actually a star whose two components have magnitudes 3.3 and 3.5. Delta Sagittarii, is a K2 spectra star with magnitude 2.71 and only 85 light years from Earth. Eta Sagittarii is a star with component magnitudes of 3.18 and 10, while Pi Sagittarii is actually a triple system whose components have magnitudes 3.7,3.8. The Bayer designation Beta Sagittarii is shared by two systems, β¹ Sagittarii, with apparent magnitude 3.96, and β² Sagittarii. The two stars are separated by 0. 36° in the sky and are 378 light years from earth, Beta Sagittarii, located at a position associated with the forelegs of the centaur, has the traditional name Arkab, meaning achilles tendon. Nova Sagittarii 2015 No.2 was discovered on March 15,2015, by John Seach of Chatsworth Island, NSW and it lies near the center of the constellation

Galaxy
–
A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias, literally milky, Galaxies range in size from dwarfs with just a few billion stars to giants with one hundred trillion stars, each orbiting its galaxys center of mass. Galaxies are categorized according to their morphology as elliptical, spiral. Many galaxies are thought to have holes at their active centers. The Milky Ways central black hole, known as Sagittarius A*, has a four million times greater than the Sun. Recent estimates of the number of galaxies in the observable universe range from 200 billion to 2 trillion or more, most of the galaxies are 1,000 to 100,000 parsecs in diameter and separated by distances on the order of millions of parsecs. The space between galaxies is filled with a gas having an average density of less than one atom per cubic meter. The majority of galaxies are organized into groups, clusters. At the largest scale, these associations are generally arranged into sheets and filaments surrounded by immense voids. In Greek mythology, Zeus places his son born by a mortal woman, the infant Heracles, on Heras breast while she is asleep so that the baby will drink her divine milk and will thus become immortal. Hera wakes up while breastfeeding and then realizes she is nursing a baby, she pushes the baby away, some of her milk spills and. In the astronomical literature, the capitalized word Galaxy is often used to refer to our galaxy, the Milky Way, to distinguish it from the other galaxies in our universe. The English term Milky Way can be traced back to a story by Chaucer c. 1380, See yonder, lo, the Galaxyë Which men clepeth the Milky Wey, For hit is whyt. However, the word Universe was later understood to mean the entirety of existence, so this expression fell into disuse and the objects instead became known as galaxies. Tens of thousands of galaxies have been catalogued, but only a few have well-established names, such as the Andromeda Galaxy, the Magellanic Clouds, the Whirlpool Galaxy, and the Sombrero Galaxy. Astronomers work with numbers from certain catalogues, such as the Messier catalogue, the NGC, the IC, the CGCG, all of the well-known galaxies appear in one or more of these catalogues but each time under a different number. For example, Messier 109 is a galaxy having the number 109 in the catalogue of Messier, but also codes NGC3992, UGC6937, CGCG 269-023, MCG +09-20-044. One of the arguments to do so is that these impressive objects deserve better than uninspired codes, for instance, Bodifee and Berger propose the informal, descriptive name Callimorphus Ursae Majoris for the well-formed barred galaxy Messier 109 in Ursa Major

Comet
–
A comet is an icy small Solar System body that, when passing close to the Sun, warms and begins to evolve gasses, a process called outgassing. This produces an atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred metres to tens of kilometres across and are composed of collections of ice, dust. The coma may be up to 15 times the Earths diameter, if sufficiently bright, a comet may be seen from the Earth without the aid of a telescope and may subtend an arc of 30° across the sky. Comets have been observed and recorded since ancient times by many cultures, Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several millions of years. Short-period comets originate in the Kuiper belt or its associated scattered disc, long-period comets are thought to originate in the Oort cloud, a spherical cloud of icy bodies extending from outside the Kuiper belt to halfway to the nearest star. Long-period comets are set in motion towards the Sun from the Oort cloud by gravitational perturbations caused by passing stars, hyperbolic comets may pass once through the inner Solar System before being flung to interstellar space. The appearance of a comet is called an apparition, Comets are distinguished from asteroids by the presence of an extended, gravitationally unbound atmosphere surrounding their central nucleus. This atmosphere has parts termed the coma and the tail, however, extinct comets that have passed close to the Sun many times have lost nearly all of their volatile ices and dust and may come to resemble small asteroids. Asteroids are thought to have a different origin from comets, having formed inside the orbit of Jupiter rather than in the outer Solar System, the discovery of main-belt comets and active centaur minor planets has blurred the distinction between asteroids and comets. As of November 2014 there are 5,253 known comets, however, this represents only a tiny fraction of the total potential comet population, as the reservoir of comet-like bodies in the outer Solar System is estimated to be one trillion. Roughly one comet per year is visible to the eye, though many of those are faint. Particularly bright examples are called Great Comets, the word comet derives from the Old English cometa from the Latin comēta or comētēs. That, in turn, is a latinisation of the Greek κομήτης, Κομήτης was derived from κομᾶν, which was itself derived from κόμη and was used to mean the tail of a comet. The astronomical symbol for comets is ☄, consisting of a disc with three hairlike extensions. The solid, core structure of a comet is known as the nucleus, cometary nuclei are composed of an amalgamation of rock, dust, water ice, and frozen gases such as carbon dioxide, carbon monoxide, methane, and ammonia. As such, they are described as dirty snowballs after Fred Whipples model

Physics
–
Physics is the natural science that involves the study of matter and its motion and behavior through space and time, along with related concepts such as energy and force. One of the most fundamental disciplines, the main goal of physics is to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy, Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the mechanisms of other sciences while opening new avenues of research in areas such as mathematics. Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs, the United Nations named 2005 the World Year of Physics. Astronomy is the oldest of the natural sciences, the stars and planets were often a target of worship, believed to represent their gods. While the explanations for these phenomena were often unscientific and lacking in evidence, according to Asger Aaboe, the origins of Western astronomy can be found in Mesopotamia, and all Western efforts in the exact sciences are descended from late Babylonian astronomy. The most notable innovations were in the field of optics and vision, which came from the works of many scientists like Ibn Sahl, Al-Kindi, Ibn al-Haytham, Al-Farisi and Avicenna. The most notable work was The Book of Optics, written by Ibn Al-Haitham, in which he was not only the first to disprove the ancient Greek idea about vision, but also came up with a new theory. In the book, he was also the first to study the phenomenon of the pinhole camera, many later European scholars and fellow polymaths, from Robert Grosseteste and Leonardo da Vinci to René Descartes, Johannes Kepler and Isaac Newton, were in his debt. Indeed, the influence of Ibn al-Haythams Optics ranks alongside that of Newtons work of the same title, the translation of The Book of Optics had a huge impact on Europe. From it, later European scholars were able to build the devices as what Ibn al-Haytham did. From this, such important things as eyeglasses, magnifying glasses, telescopes, Physics became a separate science when early modern Europeans used experimental and quantitative methods to discover what are now considered to be the laws of physics. Newton also developed calculus, the study of change, which provided new mathematical methods for solving physical problems. The discovery of new laws in thermodynamics, chemistry, and electromagnetics resulted from greater research efforts during the Industrial Revolution as energy needs increased, however, inaccuracies in classical mechanics for very small objects and very high velocities led to the development of modern physics in the 20th century. Modern physics began in the early 20th century with the work of Max Planck in quantum theory, both of these theories came about due to inaccuracies in classical mechanics in certain situations. Quantum mechanics would come to be pioneered by Werner Heisenberg, Erwin Schrödinger, from this early work, and work in related fields, the Standard Model of particle physics was derived. Areas of mathematics in general are important to this field, such as the study of probabilities, in many ways, physics stems from ancient Greek philosophy

Pinyin
–
Pinyin, or Hànyǔ Pīnyīn, is the official romanization system for Standard Chinese in mainland China, Malaysia, Singapore, and Taiwan. It is often used to teach Standard Chinese, which is written using Chinese characters. The system includes four diacritics denoting tones, Pinyin without tone marks is used to spell Chinese names and words in languages written with the Latin alphabet, and also in certain computer input methods to enter Chinese characters. The pinyin system was developed in the 1950s by many linguists, including Zhou Youguang and it was published by the Chinese government in 1958 and revised several times. The International Organization for Standardization adopted pinyin as a standard in 1982. The system was adopted as the standard in Taiwan in 2009. The word Hànyǔ means the language of the Han people. In 1605, the Jesuit missionary Matteo Ricci published Xizi Qiji in Beijing and this was the first book to use the Roman alphabet to write the Chinese language. Twenty years later, another Jesuit in China, Nicolas Trigault, neither book had much immediate impact on the way in which Chinese thought about their writing system, and the romanizations they described were intended more for Westerners than for the Chinese. One of the earliest Chinese thinkers to relate Western alphabets to Chinese was late Ming to early Qing Dynasty scholar-official, the first late Qing reformer to propose that China adopt a system of spelling was Song Shu. A student of the great scholars Yu Yue and Zhang Taiyan, Song had been to Japan and observed the effect of the kana syllabaries. This galvanized him into activity on a number of fronts, one of the most important being reform of the script, while Song did not himself actually create a system for spelling Sinitic languages, his discussion proved fertile and led to a proliferation of schemes for phonetic scripts. The Wade–Giles system was produced by Thomas Wade in 1859, and it was popular and used in English-language publications outside China until 1979. This Sin Wenz or New Writing was much more sophisticated than earlier alphabets. In 1940, several members attended a Border Region Sin Wenz Society convention. Mao Zedong and Zhu De, head of the army, both contributed their calligraphy for the masthead of the Sin Wenz Societys new journal. Outside the CCP, other prominent supporters included Sun Yat-sens son, Sun Fo, Cai Yuanpei, the countrys most prestigious educator, Tao Xingzhi, an educational reformer. Over thirty journals soon appeared written in Sin Wenz, plus large numbers of translations, biographies, some contemporary Chinese literature, and a spectrum of textbooks
